# R program to illustrate # toString function # Initializing a string vector x <- c("GFG", "Geeks", "GeeksforGeekss") # Calling the toString() function toString(x)
Output :
[1] "GFG, Geeks, GeeksforGeekss"
# R program to illustrate # toString function # Initializing a string vector x <- c("GFG", "Geeks", "GeeksforGeekss") # Calling the toString() function toString(x, width = 2) toString(x, width = 8) toString(x, width = 10)
Output:
[1] "GF...." [1] "GFG, ...." [1] "GFG, G...."
# Matrix having 3 rows and 3 columns # filled by a single constant 5 mat <- (matrix(5, 3, 3)) print(mat) str <- toString(mat) print("String") print(str)
Output:
[,1] [,2] [,3] [1,] 5 5 5 [2,] 5 5 5 [3,] 5 5 5 [1] "String" [1] "5, 5, 5, 5, 5, 5, 5, 5, 5"
